5 claims. (c1. iss- 158) `This invention relates to improvements in picker spindle lubrication and it is the general object ofthe invention to provide mechanism which `is-operated by motion of the lay to sup ply the spindle with lubricant.

In certain types of looms the shuttle is propelled by a picker which slides along a rod or spindle secured to the lay and parallel to the `shuttle box. In such looms it is desirable to provide adequate lubrication ofthe spindle to prevent excessive heating thereof bythe picker fas the latter slides along it. It is an important object `of my present invention to provide a portion at least of the picker spindle with a bore "which communicates with a tube or the like the receiving end of which extends forwardly and is *provided withV a guide 4which directs a pressure 'lubricator to theA inlet mouth of the tube.

The reciprocating lay is `in theforward part of its motion when the shuttle is boxed and the "picker is in position to start a picking stroke. It is a further object'of my present invention to provide the bore of the rpicker spindle with an VNspindle but is capable of angular adjustment frelatively thereto.

With these and other objects in view which will appear as the description proceeds, my invention resides in the combination and arrangement of parts hereinafter described and set forth.

4In the accompanying drawing, wherein'a convenient embodiment of my invention is set forth,

Fig. 1 -is a plan View of a lay having my in- `vention applied thereto,

Fig. 2 is an end elevation on an enlarged scale `looking inzthe direction of arrow 2, Fig. 1,

Fig. 3 is a detailed vertical section on an en larged scale on line 3-3, Fig. 2.,

Fig, 4 is a detailed horizontal section on an enlarged scale on line 4,-4 of Fig. 2, and

Fig. 5 is an enlarged longitudinal `section `through a portion of the pressure lubricator taken on line 5-5 of Fig. l.

Referring to the drawing, the lay I is driven ybackwa'rdly 'and forwardly by means of connectors'cneofwhich is `indicated at `I I. A lay' VVcorresponding pocket 35 in the head 32. "37 secured as at '38 to the 'lay en d has a rearend I2 projects to the left of the lay and inthe present instance is provided with inner and outer box guides I3 and I4, respectively, which receive the tongues i of a set of shifting shuttle boxes designated at I6. The boxes are mounted on a ro'd II shown in Fig. 2 and may rise and fall in response to pattern demands.

Each shuttle box is provided with a binder and binder spring -2I to hold the shuttles S therein in normally boxed position While the shuttle box is either in inactive non-picking position or when the lay is in the forward part of its stroke. A picker spindle 22 is secured at its inner or right end as viewed `in Fig. 1 to the lay end as at 23 and is also secured at its outer or left end to a support 24 carried by the lay end. A picker 25 slides along the spindle and is propelled by a picker stick 26 to move to the right as viewed in Fig. l, when the lay has reached approximately the mid point of its rearward stroke to propel the shuttle out of the box. When the lay is in forward position the picker will be located as shown in Fig. 1.

In carrying my present invention into effectY lvprovide the left'end of spindle 22 with an oil bore Si), see Fig. 3, having an outlet 3| which `lies between the ends of the picker when the latter is in the normal position shown in Fig. 1. The bore extends to a head 32 which is held -in position by a spring 33 the'right end of Which as shown in Fig, 2 is fastened to the adjacent part of the lay end by a bolt 34. The spindle has a frusto-conical end 35 which iits into Va A plate ward extension 3i)` which is threaded to receive the tapered threads of a clamping nut surrounding the spindle. The latter passes through the extension 39 and is held thereto by the nut 40."

The lower end of the head 32 has threaded thereinto a nut which surrounds a thin metal cap 46 the interior of which communicates with a vertical bore 9U in the head. This bore is also in communication with the bore 30 of the spindle so that oil may pass from the interior of Athe cap into the bore 30.

The lower end of Vthe cap is secured to a iiexible cil tight cable 41 which as shown in Fig. 2 Vmay extend downwardly and then forwardly and has the front end thereof provided with a second cap E8 similar to cap 46. Cap 48 extends through a nut 49 which is threaded into coupling 50 the front end of which is threadedas at '5I into the cylindrical rear shank 52 of a as already described and shown in Fig. 3, while the lower forward end of bore 55 is connected A by passages through cap 48 and coupling 50 tothe cavity 50 which is normally sealed by the ball 52. g

In order that lubrication of the spindle may be effected I may use any one of several available pressure lubricators and I do not wish necessarily to be limited to the form shown in Figs. l and 2. For purposes of illustration however I have set forth a pressure lubricator including a cylinder -lll into the rear end of which is fitted a cap 'll from which extends a tube l2. The rear end of thistube is provided with a nozzle 'E3 while the forward end is made with a small cylinder i4 to receive a piston l5 on the end of a rod l5, see Fig. 5. The latter rod is mounted for sliding motion with respect to the cylinder by means of bearing TI on the front wall 'I8 of the cylinder and is provided with a hand hold l. A relatively heavy compression spring 80 is located between Vthe* head 19 and the wall 'i8 to hold the head normally spaced from the cylinder and permit the piston 'l5 lto be located in forward position with respect to the cylinder le. A ball lock 8l yacted upon by a spring 82, both located in. the

tube l2, prevents return of oil from the rear part of the tube to the cylinder.

As shown in Fig. 5 the piston 'l5 is loosely .mounted on the rear end of rod 'i6 and has its A rear-end bent as at 83 to t against a valve seat 84 on the rod l5. A light compression spring 85 is located between the piston l5 and a nut d5 at Y .the rear end of rod '16. vWhen the hand hold 'I9 is pushed rearwardly with respect to the cylinder Award motion of the lay and there is a resultant rtendency to move the piston forwardly. The spring Sil, however, exerts more forcev than, the

combined force of the hydraulic pressure plus spring 35 and therefore rod 'i5 moves forward faster than piston l5, therebyopening port 5l.

As they pressureon both sides of the-valve seat equalizesAV the spring S5 will move the piston l5 forwardly until it is seated in the position shown .in Fig. 5. y

Underv normal conditions the lay moves back- -wardly and forwardly with the funnel or bell advancing with the lay. Such oil 'as may be in 4the system carried by the lay isfretained by the f 5 ball lock 62. When theattendant wishes to lubricate the picker spindle he will hold the pressure lubricator in the position indicated in Fig. land kthe' interior conical surface of the bell 53 will Vdirect the nozzle F3 against the ball G2. The rod ftinues toadvance the tube 12' and cylinder 1D move forwardly but the attendant prevents for ward motion of the head 19, thereby effecting relative rearward motion of the piston 'I5 in the cylinder M to cause oil to move rearwardly 5 through the tube l2 and around the ball lock 8l. The oil then passes rearwardly and around the ball lock 62 to enter the chamber 60 and thence moves rearwardly and upwardly as will be apparent from an inspection of Fig. 3 to the outlet 3l. This operation occurs while the lay is near vthe forward end of its motion and while the picker is in such position as to prevent oil from Isquirting or spattering out of the outlet 3|. From the foregoing it will be seen that I 15 have provided a simple form of picker spindle lubricator including a guide in the form of a bell or funnel to direct the rearward end of a pressure lubricator against a ball lock or the like. As the lay advances the oil from the cylinder 'I0 is forced rearwardly around the ball lock'62 and upwardly ,through the bore 65, through the head 32, and Yinto thebore 3l). It will also be seen that the flat spring 33 -holdsrhead' 32 seated against the endY of the spindle and presents convenient means 5 for assembling and removing the head 32. Furlthermore, the flexible tube il leads downwardly from the spindle and (all partsv of the system eX- tendingA from head 32 ytothe conical bell 53 are below boreV 35,' hence dripping of oil from outlet 3i is prevented.

A Ijaving thusA described my invention it will be seen' that changes and modifications may be made therein by those skilled in the art without departing from the spirit andV scope of the invvention and 21 do not wish to be limited to the details herein disclosed, but what I claim is: 1.
